Description of problem:

On VMPool creation from the REST API, the disconnect_action_delay property isn't copied from the template.

The request was a POST request to the URL https://{{base_url}}/ovirt-engine/api/vmpools with the body:

<vm_pool>
    <name>VMPoolShutdown</name>
    <cluster>
        <name>golden_env_mixed_1</name>
    </cluster>
    <template>
        <name>shutdown_template</name>
    </template>
    <size>2</size>
</vm_pool>


Version-Release number of selected component (if applicable):
    - Engine instance with RHV 4.5.0-6 (ovirt-engine-4.5.0.2-0.7.el8ev) and RHEL 8.6 installed.
    - 3 hosts with RHV 4.5.0-6 and RHEL 8.6 and with vdsm-4.50.0.12-1.el8ev.

How reproducible:
100%

Steps to Reproduce:

From WebAdmin:

1. Create a 4.7 data center and a 4.7 cluster.
2. Install the hosts and create a new NFS storage domain.
3. Create an RHEL VM.
4. Create a template from the VM with Console Disconnect Action set to Shutdown virtual machine and Disconnect Action Delay in Minutes set to 2.

From the REST API:

5. Create a VM Pool from the template using the below POST request to the URL https://{{base_url}}/ovirt-engine/api/vmpools with the body:

<vm_pool>
    <name>VMPoolShutdown</name>
    <cluster>
        <name>golden_env_mixed_1</name>
    </cluster>
    <template>
        <name>shutdown_template</name>
    </template>
    <size>2</size>
</vm_pool>

Actual results:
1. The 4.7 data center and the 4.7 cluster were created.
2. The hosts were installed and the NFS storage domain was created.
3. The VM was created.
4. The template was created with Console Disconnect Action Delay set to 2 minutes.
5. The VM pool was created with:
            <disconnect_action>SHUTDOWN</disconnect_action>
            <disconnect_action_delay>0</disconnect_action_delay>

Expected results:
Steps 1-4 results are as expected. 
In step 5, the Console Disconnect Action Delay property should have been set to 2 minutes.
